  VerfahrenzurHerstellungvonBogenlampenelektroden. 



   Bekanntlich wird durch Beimischung gewisser mineralischer Stoffe zu der Dochtmasse der   Kohlenstäbe   für Bogenlampen die Leuchtkraft derselben   beträchtlich   erhöht. 



   Auch ist es bekannt, dass einen Hauptbestandteil dieser mineralischen Stoffe bei fast allen in den Handel gebrachten Kohlenstäben für Effekt- oder Flammbogenlampen die Fluoride von Kalzium, Barium, Magnesium, Strontium usw. bilden, die einerseits wohl die Lichtausbeute sehr günstig beeinflussen, aber andererseits bei ihrer Verbrennung im elektrischen Lichtbogen ziemlich bedeutende Mengen von   Fluord npfen entwickeln. Abgesehen   von der zersetzenden Wirkung der letzteren auf die Metallteile der   Bogenlampen   und der dadurch verursachten raschen Abnützung der Lampen, sind   Fluordämpfe in grösseren

Dieses Mineral ist

  Process for the manufacture of arc lamp electrodes.



   It is known that the addition of certain mineral substances to the wick mass of the carbon rods for arc lamps considerably increases the luminosity of the same.



   It is also known that the fluorides of calcium, barium, magnesium, strontium etc. form a main component of these mineral substances in almost all carbon rods marketed for effect or flame arc lamps, which on the one hand have a very favorable effect on the light output, but on the other hand When burned in an electric arc, they develop quite significant quantities of fluorine cells. Apart from the corrosive effect of the latter on the metal parts of the arc lamps and the rapid wear and tear of the lamps caused by this, fluorine vapors are in larger quantities

 has only allowed rooms to a very limited extent until now.



     The purpose of the present foundation is to remedy this inconvenience by using a mineral instead of the above-mentioned fluoride, which also has a favorable effect on the luminosity of the arc to the same extent, but without developing any significant amount of harmful fumes during combustion. This mineral is
